A new suggestion that complexity increases over time, not just in living organisms but in the nonliving world, promises to ...

A longstanding question in evolutionary biology is how sexual selection influences how entire genomes develop. Sexual ...

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes ...

Each lizard is unique. Some have longer legs, others stronger jaws, and all behave slightly differently. The differences ...

Experiments like these are vital to the scientific process, but without evidence for multilevel selection in wild animals, ...

New study shows how bird traits like gene makeup and clutch size shape evolution. This may help scientists understand ...

As conditions change, so does life. It evolves. Evolution is driven by a process called natural selection. And there's no better place to see how it works than in the forests of Madagascar.

The theory of evolution is dominated by the utilitarian logic of natural selection: adapt or die, survival of the fittest.

Only a human being could make such conscious decisions. This is why the species Homo sapiens is the apex of evolution. Natural selection is at one and the same time a blind and creative process.

This is because natural selection acts to increase the prevalence ... They have had a tremendous impact on our evolution, and they, themselves, evolve over time. The great effect that pathogens ...

Our research takes place on a South Florida island roughly the size of an American football field – assuming we’re successful in sidestepping the American crocodiles that bask in the surrounding lake.

Studies have suggested that genes under strong sexual selection tend to evolve rapidly, particularly those associated with ...
